Section 4 • Operation
CAUTION
DO NOT CONTINUE TO ENERGIZE THE ACTUATOR
MOTOR AFTER THE SLIDE HAS REACHED THE
MECHANICAL STOP. Doing so may cause mechanical
damage to the motor or shear the motor shaft key.
When the slide has reached the mechanical stop
position, press the button in the center of the photo-
chopper to release the brake, and thereby release the
tension on the actuator motor.
NOTE
The “Slide calibration” screen on the Control Panel has
a “Current” window, which displays twice the actuator
output voltage. This value, (the % volume and the %
capacity) displayed in the “Current Vol” and Current
Cap” Windows are meaningless until calibration has
been completed.
10. Use the DOWN button on the Control panel to drive
the slide valve to its minimum “mechanical stop”
position. Release the DOWN button when the slow-
ing of the motor rotation and a winding sound from
the actuator motor is noted.
11. Press down on the photo-chopper shaft to disen-
gage the brake, releasing tension from the motor
mount, see Figure 4-5. Use the UP button to pulse
the actuator to where the slide is just off of the me-
chanical stop and there is no tension on the motor
shaft.
12. Quickly press and release the blue button on the ac-
tuator again. The red LED will now fl ash at a slower
rate, indication that the minimum slide valve posi-
tion (zero position) has been set.
13. Use the UP button on the Control panel to drive the
slide to its maximum “mechanical stop” position.
Release the UP button when the slowing of the mo-
tor rotation and a winding sound from the actuator
motor is noted.
14. Press down on the photo-chopper shaft to disen-
gage the brake, releasing tension from the motor
mount. Use the DOWN button to pulse the actua-
tor to where the slide is just off of its mechanical
stop and there is no tension on the motor shaft.
15. Quickly press and release the blue button on the
actuator one more time. The red LED will stop
fl ashing. The actuator is now calibrated and knows
the minimum and maximum positions of the slide
valve it controls. Now the capacity or volume chan-
nel of the PLC can be calibrated.
16. Use the DOWN button to move the actuator to-
wards its minimum position while watching the mV
readout on the Control Panel screen. Discontinue
pressing the DOWN button when the mV reading
the “Current” window above the “Set Min” button
is approximately 500 mV.
17. Now use the DOWN or UP buttons to position the
slide valve until a value close to 300 mV is on the
screen. Then, press the “Set Min” button in the ca-
pacity or volume slide valve window to tell the con-
troller that this is the minimum mV position. Note:
The value in the “Current Cap” or “Current Vol” win-
dow has no meaning right now.
18. Use the UP button to rotate the actuator towards its
maximum position while watching the mV readout
on the controller screen. Discontinue pressing the
UP button when the mV reading in the “Current”
window is approximately 4800 mV. You are nearing
the mechanical stop position.
19. Pulse the UP button to carefully move the slide
valve until the mV readout “saturates”, or stops in-
creasing. This is around 4800 mV Record mV maxi-
mum reading.
20. Pulse the DOWN button until the mV just start
to decrease. (This is the point where the channel
drops out of saturation). Adjust mV value to 300
mV below recorded maximum mV.
21. Press the “Set Max” button.
22. Press the “Main” button to complete calibration
and exit the “Slide Calibration” screen. The con-
troller will automatically energize the actuator and
drive it back to its minimum position (below 5%) for
pre-start-up.
NOTE
Now the “Current Cap” or the “Current Vol” value will
be displayed in the window on the “Main” screen and
the “Slide Calibration” screen.
23. Gently lower the plastic cover over the top of the
actuator to where it contacts the base and O-ring
seal.
CAUTION
Do not over tigten screws. Failure to comply may
result in damage to equipment.
24. Check and make sure the cover is seated properly,
then gently tighten the four #10 screws.
25. Enable the “Slide Non-Movement Alarm” by going
to the “Setup” menu and choosing “Alarm Enable”
for the “Slide Non-Movement Option”.
26. Repeat procedure to calibrate other slide valve
actuator.
